I would advise against number two.   Unless you have at least 2 DBA's
per environment end-to-end.   The problem is coverage for sick days,
vacations, training, etc.

Are DBA's allowed to move between groups?  ie, in your current
environment, are DBA's allowed to switch from infrastructure to

Personally I like to support an environment end to end.  Even if you
break them apart like the options you propose there may be some

The best DBA group I was a part of was structured in an end-to-end
fashion but once a year we had to juggle the environments.  ie, there
were around 10 DBA's supporting multiple environments each.  At the
end of the year you could elect to keep a couple of the environments
but the rest went into a pool.   Then we went around the room and each
DBA picked a new environment from the pool that they would like to
support. This solved the coverage issue and seemed to keep everyone
